:VPAPE'R-FASTENER. i

Specification of Letters Patent. Application filed F brua y 24, 1906.Serial no. 302.698.

Patented Oct. 30, 1906.

To all whom itmay concern: Be it known that I, JOSEPHICLAYTON Lo- I GAN,:a citizen of the United States, residing at Atlanta, in the county ofFulton and State ofGeorgia, have invented a new and usefulPaper-Fastener, of which the following is a specification. C.

This invention relates to paper-fasteners, and has for-its object toprovide a comparatively simple, and inexpensive fastener for holdingtogether a file of papers which must be added to from time to time andfor receiving such additional papers as are necessary to complete thefile.

A further object of the invention is to provide a fastener the shank ofwhich is provided. with a terminal point adapted to pierce the paperstobe filed, said shank being locked in-engagement with the papers by aremovable'cap or disk.

. A further object is to form the cap with oppositely-disposed springlocking members adaptedto engage the pointed terminal of the shank, andthereby prevent accidental displacementof the same.

A- still further object of the invention is to generally improve thisclass of devices so as to increase their utility, durability, andefficiency, as well as to reduce the cost ofmanufacture. I i

With these and other objects in view the invention consists inthe'construction and novel-combinationand arrangement of partshereinafter fully described, and illustrated in theaccompanyingdrawings, it being understood that various changes in form,proportions, and minor details of construction may be resorted to withinthe scope of the appended-claims.

In'the accompanying drawings, forming a part of. this specification,Figure 1 is a perspective 'view 'of the piercing member or shank of thefastener. Fig. 2 is a similar view showing the base in. position on theshank. Fig. 3 is a top plan view ofthe locking-cap detached. Fig. 4 is aperspective view showing the cap in position on the shank or iercingmember.

imilar characters of reference indicate corresponding parts in all ofthe figures of the drawings.

The improved fastener comprises a shank or body portion 1), preferablyformed of a single strip of metal or other suitable material,

one end of which is provided with a piercing point, while the oppositeend thereof isbent upon itself and extended laterally in oppositedirections to .form a base a.

Associated with the shank b is a cap or looking member, c, preferablycircular in form, :asshown, and provided with an elongated slot oropening e .for the receptionof theshank b and having its sidewallsextended inwardly to form central projections h, adapted to engage theshank b when the rlatter is bent downwardly ontop of the cap, as bestshown in Fig. 4 of the drawings.

The cap 0 is provided with oppositely-disposed concentriccircumferential slits 'L,

spaced inwardly from the peripheryof the cap, the severed portion of thecapbeing upstruck and spaced from-the top of the latter, thereby to formspring locking members d, adapted to. receive the pointed terminal oftheshank b, as shown.

The locking-members d are each provided with ofiset portions orshoulders 1', adapted to engage the adjacent longitudinal edge of theshank b when the cap is rotated thereby to limit the rotary movement ofsaid cap. In some casesthe shank (1 may be provided with a plate or diskf, the marginal edge of which is bent upwardly to form an annular flange7c, adapted to bear against the basea, and thereby lock the partstogether.

In operation the ointed end of the shank b is threaded throug theprescriptions, bills,

or other papers to be filed and thence passed through 1 the opening eand bent substantially at right angles, as shown. The cap a is thenartially rotated, which causes the adj acent ocking member or lip d toengage the pointed terminal of the shank, and thus hold the severalpapers securely bound together.

In order to release the papers or to add additional papers to the file,it is merely necessary to rotate the cap 0 in the opposite direction,when the pointed end of the shank b will be released from the lockingmember d, thus permitting the same to be bent laterally to aperpendicular position and the cap 0 removed, so as to permit the filingof the additional papers.

Attentlon is called to the fact that the projections it have a tendencyto bite into the walls of the shank b, and thus assist in holding theshank in bent or locked position, while the size of the opening epermits the cap to be partially rotated, so as to release or look theFrom the foregoing description it will be seen that there is provided anextremely simple, inexpensive, and efficient device admirably adaptedfor the attainment of the ends in view.

What I claim is 1. A paper-fastener comprising a shank having a pointedterminal, and a ca provided with an opening adapted to receive the shankand having circumferential concentric slits formed therein, the metal atsaid slits being upstruck and spaced from the cap for engagement withthe pointed terminal of the shank.

2. A paper-fastener comprising a shank, and a cap having an elongatedslot formed therein for the reception of the shank and rovided withoppositelydisposed spring ocking members adapted to engage said shank,there being rojections extending inwardly from the wails of the slot andadapted to bear against the shank.

3. A paper-fastener comprising a shank having a pointed terminal, a caphaving a central opening formed therein for the reception of the shankand provided with concentric slits disposed inwardly from the peripheryof the cap, the metal at said slitsbeing upstruck and provided withoffset portions defining spring locking members adapted to engage thepointed terminal of the shank.

4. A paper-fastener comprising a shank having one endthereofbent uponitself and extending laterally in opposite directions to form a base andits opposite end provided with a pointed terminal, a cap having acentral opening formed therein for the reception of the pointed end ofthe shank and provided with oppositely-disposed spring locking membersdisposed concentric with the opening in the plate and adapted to engagesaid shank.

5. A paper-fastener comprising a shank having one end thereof bent uponitself and extended laterally in opposite directions to form a base andits opposite end provided with a pointed terminal, a cap comprising afiat metal disk having an elongated opening formed in the center thereoffor the reception of the shank and provided with concentriccircumferential slits spaced inwardly from the periphery of the cap andstruck up to form spring locking members adapted to engage the shank.

6. A paper-fastener comprising a shank having one end thereof bent uponitself and extended laterally in opposite directions to form a base andits op osite end provided with a pointed termina a plate secured to thebase, and a cap com rising a circular metal disk having an elhngatedopening formed in the center thereof for the reception of the shank andprovided with concentric circumferential slits spaced inwardly from theperiphery of the disk and upstruck to form spring locking membersadapted to engage the pointed terminal of the shank, the walls of theslot being provided with inwardly-extending projections adapted to bearagainst the shank when the latter is in engagement with the adjacentlocking member.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
